Fig 24-7 Typical QoS topology
As shown in the figure, inside the block is a QoS domain, SwitchA classifies different
traffics and assigns different IP precedences. For example, set IP precedence for packets
from segment 192.168.1.0 to 5 on port ethernet 1/1. The port connecting to switch2 is a
trunk port. In SwitchB, set port ethernet 1/1 that connecting to swtich1 to trust IP
precedence. Thus inside the QoS domain, packets of different priorities will go to different
queues and get different bandwidth.
The configuration steps are listed below:
QoS configuration in Switch1:
Switch#config
Switch(config)#access-list 1 permit 192.168.1.0 0.0.0.255
Switch(config)#mls qos
Switch(config)#class-map c1
Switch(config-ClassMap)#match access-group 1
Switch(config-ClassMap)# exit
Switch(config)#policy-map p1
Switch(config-PolicyMap)#class c1
Switch(config--Policy-Class)#set ip precedence 5
Switch(config--Policy-Class)#exit
Switch(config-PolicyMap)#exit
Switch(config)#interface ethernet 0/0/1
Switch(Config-Ethernet0/0/1)#service-policy input p1
QoS configuration in Switch2：
Switch#config
Switch(config)#mls qos
